C6xx Titan OLT initial steps

On this page

This guide provides step-by-step instructions for the initial OLT configuration and for setting up IP connectivity of the ZTE TITAN C6xx Series OLTs. After completing these steps, you'll be ready to connect your OLT to SmartOLT.

Step 1: Connect to the OLT via Serial Console

There is no factory IP address and usually no default user/pass like zte/zte, so the initial configuration must be done by serial terminal.

Requirements:

  • The original ZTE serial cable provided in the C6xx box (special pinout)
  • Serial-to-USB converter (if necessary)
  • PC with terminal software like PuTTY

Connection Setup:

  1. Connect the ZTE serial cable to the CON port of the OLT
  2. Connect the other end to your PC (using Serial-to-USB converter if needed)
  3. Use PuTTY with parameters: 115200-8-N-1
  4. To find the correct COM port, check Device Manager in Windows (Windows+X) under Ports (COM&LPT)
  5. Also connect the OLT and Router with a LAN cable using the MGMT port (in the same group with CLK, ALM and CON ports)

Note: The MGMT port is an isolated port (OOB - Out Of Band) designed for management purposes only. This port cannot be used to transport customer traffic.

Step 2: Configure IP Address and Default Gateway

Configure an IP address on the mgmt_eth interface and add a default gateway, then save the configuration.

Note: The default gateway must be added in "vrf mng" only if the management interface (mgmt_eth) will be used. If you use a VLAN interface for management, "vrf mng" is not necessary.

ZXAN# conf t
ZXAN(config)# interface mgmt_eth
ZXAN(config-if)# ip address [IP] [Netmask]
ZXAN(config-if)# exit
ZXAN(config)# ip route vrf mng 0.0.0.0 0.0.0.0 [IP of the GATEWAY]
ZXAN(config)# exit
ZXAN# write
Write DB OK!

....[OK].
ZXAN#

Verify Card Status:

ZXAN# show card

1     6    PRSF    PRSF         0    V1.0.0  INSERVICE

Step 3: Create Authentication Template and User Account

Create a local authentication template and a dedicated username/password that will be used by SmartOLT to connect to your OLT.

conf t
aaa-authentication-template 2001
aaa-authentication-type local
exit

aaa-authorization-template 2001
aaa-authorization-type local
exit

system-user
authorization-template 1
bind aaa-authorization-template 2001
local-privilege-level 15
exit

authentication-template 1
bind aaa-authentication-template 2001
exit

user-name smartoltusr
bind authentication-template 1
bind authorization-template 1
password [a strong generated password]
exit

Step 4: Enable Telnet

conf t
line telnet server enable

At this stage, your OLT is ready to be interconnected with SmartOLT system.

SmartOLT Integration:

  1. Open your smartolt.com site
  2. Go to Settings → OLTs → Add OLT
  3. Fill in the required fields
  4. Click the Save button

Additional Settings

If you use SmartOLT, these are configured automatically; no need to configure them manually:

conf t
auto-write everyday 18:00:00
ntp server 20.101.57.9 priority 1 version 4
ntp server 216.239.35.4 priority 2 version 4
ntp enable

Optional: In-Band Management Configuration

You can configure an "in-band" IP address on a VLAN interface. This is useful when you want to manage the OLT using the same physical interface used for customer traffic.

Not Recommended: If a loop occurs in the ONT undetected by the ONT/OLT and the uplink port is shutdown by the uplink device, you will lose IP connectivity with the OLT.

conf t
vlan 300
exit
interface vlan300
ip address [IP] [MASK]
exit
ip route 0.0.0.0 0.0.0.0 [IP OF THE GATEWAY]

Remember! The VLAN must be tagged on the Uplink that will be used:

conf t
interface xgei-1/10/1
switchport mode trunk
switchport vlan 300 tag
exit

Useful Commands

Check the routing table:

ZXAN# show ip forwarding route

Delete existing default gateway and add a different one:

ZXAN# conf t
ZXAN(config)# no ip route 0.0.0.0 0.0.0.0
ZXAN(config)# ip route 0.0.0.0 0.0.0.0 [IP OF THE GATEWAY]
